Default frame shit is 10ms, change this in Properties | Pitch contour

There's need for manual page here! This info below is cut from

http://www.speech.kth.se/snack/man/snack2.2/tcl-man.html#spitch

For ESPS the output list will contain 4 fields for each frame, pitch, probability of voicing, local root mean squared measurements, and the peak normalized cross-correlation value that was found to determine the output pitch value.

frame (window) length is 7.5 ms and currentl there is no option to change it, needs a simple source fix. Will make a note of that.
